Abstract

The invention relates to a mechanical coding lock for an electrical power system and in particular relates to an intelligent full-sealing five-prevention lockset. The intelligent full-sealing five-prevention lockset comprises a lock case and a U-shaped locking handle, wherein two locking handle pipes are arranged in the lock case, one end of the U-shaped locking handle stretches into one locking handle pipe, a spring is connected between the end, in which the U-shaped locking handle stretches into, of the U-shaped locking handle and the locking handle pipe, a through hole is formed in the other end of the U-shaped locking handle, a locking Hall pressure sensor is arranged at the bottom end in the other locking handle pipe in the lock case, a linear motor, an RFID encoder, a singlechip, a receiving-transmitting module and a storage battery are also arranged in the lock case, the receiving-transmitting module is connected with the singlechip which is connected with the linear motor, an unlocked Hall pressure sensor and a locked Hall pressure sensor are arranged in the lock case, and the locking Hall pressure sensor, the unlocked Hall pressure sensor and the locked Hall pressure sensor are all connected with the singlechip. The lockset can only be unlocked by a computer key, and workers are prevented from unlocking arbitrarily, and can solve the problem of the wrong locking sequence by use of the computer key.

Description

technical field [0001] The invention relates to a mechanical coding lock used in an electric power system, in particular to an intelligent fully sealed five-proof lock. Background technique [0002] The microcomputer anti-misoperation locking device has been widely used in substations and power plants for many years. It is mainly composed of an anti-mistake host computer or an analog screen, a computer key and supporting five-proof locks. Among them, the supporting five-proof locks mainly include mechanical coded locks and electric locks. The mechanically coded lock has a mechanical lock core, and generally uses an RFID code chip as the lock code. After the computer key recognizes the lock code, the computer key activates the unlocking mechanism to drive the five-proof lock mechanical lock core to rotate to unlock, and the computer key stores the normal unlocking of the equipment. Sequence, that is, the computer key can be used to unlock the locks in the correct order, so as...
